SigmaCheck2Eddy Current (ECT)Conductivity Meter

The SigmaCheck2 Eddy Current (ECT) Conductivity Meter is designed to provide the user with fast and accurate conductivity measurements at a reasonable price.

The SigmaCheck2 EC Conductivity Meter is extremely easy to use making it suitable for use by shop inspectors or engineers.

The SigmaCheck2 ET Conductivity meets the requirements for conductivity measurements in the Aircraft manufacture and maintenance fields where conductivity measurements are used to verify proper alloy/temper or detect heat damaged components. The SigmaCheck2 Eddy Current Conductivity Meter is also useful to determine the purity of precious metals (counterfeit detection) such as gold bullion and coins.

Monitoring of deposition process for non ferrous material on a non-ferrous substrate

Monitoring the condition of highly stressed parts

Forged/plated material detection

The SigmaCheck2 EC Conductivity Meter has a large, color, LCD display that is easily seen in all lighting conditions.

The SigmaCheck2 is easy to hand-hold due a sculpted housing designed to fit in your hand and a convenient size and weight; only ¾ of a pound (350g) and measuring less than 6 ½” tall x 3 ¼” wide x 1” thick (163 x 80 x 25mm). A removable, silicon rubber boot is included to protect the instrument in rough environments. The standard Probe has been designed to comfortably fit the hand of the user.

The SigmaCheck2 ET Conductivity Meter has a standard operating frequency of 60 kHz and auxiliary frequencies of: 120, 240, 480 and optional 960kHz can be selected when necessary for testing thin materials with the standard probe.

Field Exchangeable Probes via SD Card

True USB PC Connectivity for remote control and data logging.

The USB Connection allows easy charging of the Instrument without having to swap the batteries.

Probe must be in thermal equilibrium with test material, and instrument and probe stabilized prior to testing Minimum 15-minute warm up time for stabilisation. At 20°C: 0-20% IACS: ± 0.05 IACS At 20°C: >20% IACS ± 0.25% of readout

Removable 2GB micro SD Card allowing over 1 million readings to be stored.

PC Connectivity

USB port for charger and PC communications

Probes

13mm diameter for 60 kHz to 480 kHz 8mm probe operates at 60 kHz to 480 kHz Probes are interchangeable with simple operator resetting procedure. Probes are field exchangeable and do not require return to manufacturer for calibration.

Accessories

A range of conductivity reference standards traceable to US and European standards are available for in field use. Up to five can be mounted on an aluminium anodised Setting Reference Blocks Holder (Part number: ASIG003)

The conductivity of each reference standard is determined for the central area of diameter 15mm of front face by comparison with similar material, the conductivity of which has been determined in terms of traceable electrical standards.

All supplied blocks are calibrated and that the certification of the equipment used for this purpose is traceable to the National Physics Laboratory (NPL) and the National Institute of Standards and Technology under NIST and calibrated in accordance to ASTM B193-02.
